Now let us note that the quantum spectral curve (REF ) is the curve for a matrix model, namely for the conformal matrix model [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]}, [14]}:
\(G_4(0,q,1,\infty )=q^{2\alpha _1\alpha _2}(1-q)^{2\alpha _2\alpha _3}\int \prod _i {\rm d}u_i \Delta ^{2b^2}(u)u_i^{2b\alpha _1}(1-u_i)^{2b\alpha _3}(q-u_i)^{2b\alpha _2},\)
